PIO means Programmed Input/Output. Rather than having the BIOS issue a series of commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the controller what it wants and then let the controller and the CPU perform the task by themselves.
Your system supports five modes, numbered from 0 through 4, which differ primarily in timing. When "Auto" is selected, the BIOS will choose the best available mode.
The options are: Auto, (Default), Disabled.
Primary/Secondary Master/Slave Ultra DMA
DMA means Direct Memory Access. Ultra DMA is faster than DMA. DMA is a method of transferring data to or from memory at a fast rate, without involving the CPU.
When you select "Auto", the BIOS will choose the best available mode.
The options are: Auto (Default), Disabled.
IDE Burst Mode
When enabled, data transfer on IDE buses will improve.
The options are: Disabled (Default), Enabled.
IDE HDD Block Mode
This allows your hard disk controller to use the fast block mode to transfer data to and from your hard disk drive (HDD).
The options are: Enabled (Default), Disabled.
Onboard FDD Controller
When enabled, the floppy disk drive (FDD) controller is activated.
The options are: Enabled (Default), Disabled.
